REVIEW
Ankit Sarin, Lee-Lynn Chen, Elizabeth C Wick
In this review, we explore the rationale and history behind the practice of preoperative fasting in elective surgery including the gradual move toward longer fasting and the more recent change in direction of practice. Gastric emptying physiology and the metabolic effects of prolonged fasting and carbohydrate loading are examined. Most recent guidelines related to these topics are discussed and practical recommendations for implementing these guidelines are suggested.

The current guidelines for preoperative fasting recommend intervals of 6, 4, and 2 h (6-4-2) of fasting for solids, breast milk, and clear fluids, respectively. The objective is to minimize the risk of pulmonary aspiration of gastric contents, but also to prevent unnecessarily long fasting intervals. Pulmonary aspiration is rare and associated with nearly no mortality in paediatric anaesthesia. The incidence may have decreased during the last decades, judging from several audits published recently. However, several reports of very long fasting intervals have also been published, in spite of the implementation of the 6-4-2 fasting regimens...

BACKGROUND: In the last 2 decades, the effectiveness of cricoid pressure (CP) in occluding the esophageal entrance has been questioned. Recent magnetic resonance imaging studies yielded conflicting conclusions. We used real-time visual and mechanical means to assess the patency of the esophageal entrance with and without CP in anesthetized and paralyzed adult patients. METHODS: One hundred seven, nonobese ASA physical status I and II patients were recruited for the study...

REVIEW
M Ramez Salem, Arjang Khorasani, Ahed Zeidan, George J Crystal
Since cricoid pressure was introduced into clinical practice, controversial issues have arisen, including necessity, effectiveness in preventing aspiration, quantifying the cricoid force, and its reliability in certain clinical entities and in the presence of gastric tubes. Cricoid pressure-associated complications have also been alleged, such as airway obstruction leading to interference with manual ventilation, laryngeal visualization, tracheal intubation, placement of supraglottic devices, and relaxation of the lower esophageal sphincter...

Awake tracheal intubation has a high success rate and a favourable safety profile but is underused in cases of anticipated difficult airway management. These guidelines are a comprehensive document to support decision making, preparation and practical performance of awake tracheal intubation. We performed a systematic review of the literature seeking all of the available evidence for each element of awake tracheal intubation in order to make recommendations. In the absence of high-quality evidence, expert consensus and a Delphi study were used to formulate recommendations...

BACKGROUND: The goal of this study was to assess the value of the 3-3 rule and the 3-3-1 rule in predicting difficult airways. METHODS: The authors conducted an observational study over a 6-month period. For each consenting adult patient undergoing general anesthesia, preoperative patient characteristics and data regarding difficult airway assessments and airway outcomes were collected. The 3-3-2 rule, 3-3-1 rule and 3-3 rule were included in preoperative difficult airway assessments...

BACKGROUND: Assessment of the potentially difficult airway (DA) is a critical aspect of resident education. We investigated the impact of a new assessment form on airway prediction and management by anaesthesia residents. We hypothesized that residents would demonstrate improvement in evaluation of DAs over the study duration. METHODS: After IRB approval, anaesthesia residents were randomized into two groups: control (existing form) and experimental (new form). Data were collected prospectively from August 2008 to May 2010 on all non-obstetric adult patients undergoing non-emergent surgery...

BACKGROUND: Difficult-airway prediction tools help identify optimal airway techniques, but were derived in elective surgery patients and may not be applicable to emergency rapid sequence intubation (RSI). The HEAVEN criteria (Hypoxemia, Extremes of size, Anatomic abnormalities, Vomit/blood/fluid, Exsanguination, Neck mobility issues) may be more relevant to emergency RSI patients. OBJECTIVE: To validate the HEAVEN criteria for difficult-airway prediction in emergency RSI using a large air medical cohort...

BACKGROUND: The Mallampati classification (MLPT) is normally evaluated in the sitting position. However, many patients cannot be evaluated in the sitting position for medical reasons. Thus, we compared the MLPT in sitting and supine positions in predicting difficult tracheal intubation (DTI). We hypothesized that the diagnostic accuracy of the MLPT performed in sitting and supine positions would differ. METHODS: We performed a single-center prospective observational study in adult patients who received general anesthesia and orotracheal intubation for noncardiac surgery...

COMPARATIVE STUDY

BACKGROUND: The Mallampati examination is a standard component of an airway risk assessment. Existing evidence suggests that cervical spine extension improves the predictive power of the Mallampati examination for detecting difficult laryngoscopy and tracheal intubation, but a comparative effectiveness study has not been conducted. METHODS: The extended Mallampati examination (EMS) was introduced to the standard preoperative airway assessment, in addition to the standard Modified Mallampati examination (MMP)...

PURPOSE: Nebulized L-epinephrine has been recommended for the treatment of viral croup. However, the few studies assessing its effect on post-extubation stridor (PES) have shown conflicting results. We compared the efficacy and safety of nebulized L-epinephrine at three different doses for the treatment of PES. PATIENTS AND METHODS: We conducted a prospective, randomized, double-blind trial including all consecutive children with a PES score of ≥4 (Westley score)...

PURPOSE: Hypotension and decreased cardiac output (CO) are common adverse effects during anesthesia induction depending on the patient's pre-anesthetic cardiac condition. The aim of this study was to assess the ability of hydroxyethyl starch (HES) 130/0.4 to prevent hypotension and decreased CO during the induction of general anesthesia. METHODS: Ninety patients undergoing laparoscopic surgery were randomly divided into a HES group and a crystalloid group. Following the insertion of an intravenous line, fluid was administered to each patient at a rate of 25 ml/min using either crystalloid or HES 130/0...

BACKGROUND: Atraumatic needles have been proposed to lower complication rates after lumbar puncture. However, several surveys indicate that clinical adoption of these needles remains poor. We did a systematic review and meta-analysis to compare patient outcomes after lumbar puncture with atraumatic needles and conventional needles. METHODS: In this systematic review and meta-analysis, we independently searched 13 databases with no language restrictions from inception to Aug 15, 2017, for randomised controlled trials comparing the use of atraumatic needles and conventional needles for any lumbar puncture indication...

Jon Lurie, Christy Tomkins-Lane
Lumbar spinal stenosis (LSS) affects more than 200,000 adults in the United States, resulting in substantial pain and disability. It is the most common reason for spinal surgery in patients over 65 years. Lumbar spinal stenosis is a clinical syndrome of pain in the buttocks or lower extremities, with or without back pain. It is associated with reduced space available for the neural and vascular elements of the lumbar spine. The condition is often exacerbated by standing, walking, or lumbar extension and relieved by forward flexion, sitting, or recumbency...

BACKGROUND: The prevalence of chronic low back pain and related disability is rapidly increasing as are the myriad treatments, including epidural injections. Even though epidural injections are one of the most commonly performed procedures in managing low back and lower extremity pain, starting in 1901 with local anesthetic alone, conflicting recommendations have been provided, despite the extensive literature. Recently Chou et al performed a technology assessment review for Agency for Healthcare Research and Quality (AHRQ) part of which was published in Annals of Internal Medicine showing lack of effectiveness of epidural steroid injections in managing lumbar radiculopathy and spinal stenosis...

BACKGROUND AND OBJECTIVE: Epidural corticosteroid injections (ESIs) have been used for several decades and now represent the most common intervention performed for the management of back pain with a radicular component. However, several reports have presented devastating complications and adverse effects, which fuelled concerns over the risk versus clinical effectiveness. The authors offer a comprehensive review of the available literature and analyse the data derived from studies and case reports...

Cervical interlaminar epidural steroid injections (ESIs) are commonly performed as one part of a multi-modal analgesic regimen in the management of upper extremity radicular pain. Spinal epidural hematoma (SEH) is a rare complication with a reported incidence ranging from 1.38 in 10,000 to 1 in 190,000 epidurals. Current American Society of Regional Anesthesia (ASRA), American Society of Interventional Pain Physicians (ASIPP), and the International Spine Intervention Society (ISIS) recommendations are that non-steroidal anti-inflammatory drugs (NSAIDs) do not need to be withheld prior to epidural anesthesia...

There are several nonsurgical alternatives to treat radicular pain in degenerative lumbar spinal stenosis. Epidural steroid injections have been used for several decades, but the different studies have shown variable effects. Searching in Epistemonikos database, which is maintained by screening 30 databases, we identified nine systematic reviews including seven pertinent randomized controlled trials. We concluded epidural steroid injection probably leads to little or no effect on reducing radicular pain of spinal stenosis...
